Are there any personal hygiene habits that you need to improve? If so,
what are they? What are you going to do to improve these habits?
a. What are germs?
Germs are tiny living organisms that are too small to be seen by the
naked human eye. There are four major types of germs: bacteria, viruses,
fungi, and protozoa. Some of these germs can cause disease.
Bacteria are tiny, one-cell creatures that get nutrients from their
environments in order to live. In some cases that environment is a human
body. Bacteria can reproduce outside of the
body or within the body as they cause
infections. Some infections bacteria cause
include sore throats, ear infections, cavities,
and pneumonia. Cholera is caused by a
bacterium that has infected water.

Viruses need to be inside living cells to grow and reproduce. Most viruses
can't survive very long if they're not inside a living thing like a plant,
animal, or person. Whatever a virus lives in is called its host. When
viruses get inside people's bodies, they can spread and make people sick.
Viruses cause chickenpox, measles, flu, and many other diseases. Because
some viruses can live for a while on something
like a doorknob or countertop, be sure to wash
your hands regularly! Rotavirus, a very
dangerous stomach illness, is caused by a virus
that has infected food.

Fungi are multi-cell, plant-like organisms. Unlike other plants, fungi
cannot make their own food from soil, water, and air. Instead, fungi get
their nutrition from plants, people, and animals. They love to live in damp,
warm places, and most fungi are not dangerous. An example of something
caused by fungi is athlete's foot, that itchy rash that teens and adults
sometimes get between their toes.
Protozoa are one-cell organisms that love moisture and often spread
diseases through water. Some protozoa cause intestinal infections that
lead to diarrhoea, nausea, and belly pain.
